For the identified problem areas along the drainage channels, study and analyze <br />alternatives for drainage improvements, with an initial focus of channel improvements, <br />driveway culvert replacement/improvements, downstream culvert replacements, <br />detention, other structural improvements to portions of the watershed and any needed <br />mitigation. <br />2. Determine the additional drainage right -of -way requirements for the improvements <br />described in items above. A maintenance berm requirement around any planned channel <br />improvements where required and on both side of channel improvements will be <br />evaluated for determining needed right- of-way. <br />Task #8 - Report Recommendations <br />1. Prepare construction cost estimates and implementation plan for the feasible alternatives. <br />2. Evaluate benefits and costs. <br />3. Provide recommendations for drainage improvements. <br />d. Prepare a Preliminary Engineering Report that documents the items described above and <br />includes supporting data as applicable. This report is intended to be used in conjunction <br />with the previously prepared Master Drainage Plan. The report will include text, tables <br />and exhibits along with some supporting data. A goal of this report will be to minimize <br />channel construction or improvements and to develop a program that could be <br />implemented by the City. The cost for the recommended improvements may exceed the <br />available funds of $900K from the City. A phased approach may be recommended to the <br />City to allow for some improvements to be considered for construction now and to <br />provide some thoughts for implementation of future drainage improvements. <br />5. Present ten printed copies and a PDF version of the draft plan to staff and council for <br />review and comments. <br />6. Incorporate applicable changes to the draft report and models from council and staff <br />comments. <br />7. Submit ten printed copies and PDF version of the final report to the City for distribution, <br />8. Attend monthly meetings, perform project management and conduct quality control. This <br />will include a workshop with Council. This scope does not include meetings where the <br />final recommended plan is presented to Harris County nor to Harris County Flood <br />Control District. <br />ESTIMATED BUDGET <br />A cost with a not to exceed amount of $166,120 is recommended for the above services <br />which also includes engineering, surveying costs, soils investigation costs and environmental <br />
